Shoreline Excavation and Grading Co. in Alpine operates under CSLB #1120830 from its Alpine Blvd mailing address, specializing in residential excavation, pool and spa digs, and custom backyard grading across San Diego County. Scope of work includes foundation excavation, precision grading for drainage and erosion control, and trenching for water, sewer, and electrical utilities — underground infrastructure that precedes perimeter installation by Arrow Fence on Petra Way in Alpine. The operation handles land clearing, demolition with debris removal, and retaining-wall site preparation for properties on Alpine's hillside terrain near Cleveland National Forest. Erosion-control solutions address slope stabilization, swale grading, and drainage-channel construction — critical scope on rural Alpine lots where subsurface water and sewer connections are coordinated with McGuire Plumbing Inc. on Alpine Blvd. Highest-value projects include multi-depth pool-and-spa combination excavations with benched shoring, engineered retaining-wall keyway cuts into native soil per geotechnical specifications, and full-lot rough grading to pad elevation with compaction testing to 90-percent relative density.
